The YouTuber does not want to admit that his system could sound a lot better with upgraded speaker wire as he does not want to put that cost burden on the system. This is the dilemma we go through every day in this hobby.
Yes and once I figured out what was going on that was pretty much the end of multi-channel for me. Unfortunately not until after wasting a good two years of my life trying to have the proverbial dual-use system. Did eventually figure out how to do it. Unfortunately while everyone likes to pretend they think and reason and figure stuff out the truth more often than not is they just copy the other guy. So all these guys like this one pretending cables don't matter only wind up deceiving a lot of regular guys who really would like good sound but just aren't up to blazing their own trail.
